The 20 Gauge Laser Bore Sighter is a device that will allow you to easily sight in your 20 Gauge Shotgun. Simply turn the laser bore sighter on and insert it into the chamber of your shotgun. Once you see the laser dot align your scope so that the dot is in the crosshairs and you're now on target for your next hunt.
The 20 Gauge Laser Bore Sighter providers a quick and easy method for sighting in 20 Gauge shotguns. Chamber the laser bore sight just like a standard shell and look for the laser dot for a visible indicator. Dial your scope in so that the laser dot is centered in your scope and you will know your scope is zeroed in at the distance you want for your next trip to the range.
I jumped on this and many other cal bore sighters while the price was right and they were all in stock. I still don't have a rifled 20 gauge barrel, but it let me know where my Benelli should be throwing groups.
mossberg 500 sight in
Helped with sighting in my mossberg 500 28inch ribbed hunting shotgun with cantilevered scope. Definitely saved some time and money than sighting in with slugs. Battery has long life!
Works for me

Used one of these bore sighters to sight in my H&R 20ga for deer hunting. I used the bore sighter to line up my scope at 70 yds and I was pretty much dead on out to 100. With a little more fine tuning and I'm driving tacks at 150yds without any problems.
